HAT-IRONING MACH'lNE.

SPECIFICATION forming part of Letters Patent No. 246,297, dated August 30, 1881,

Application filed Juiyi, iesi. (No model.)

To all whom 'it may concern Be it known that l, ALBERT DE LASKI, of Concord, county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Hat-lroningMachines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention has for its object the production of a hat-ironing machine in which the iron may be efficiently and rapidly heated 'by a combined gas and air flame, the iron being mounted so as to be universally movable, to thus adapt the iron to the shape of the crown of the hat to be operated upon, the hat-block being mounted upon what is known as an oval lathe,7 to thus enable the crown, more or less oval or round in shape, to be ironed.

My invention consists in the combination and arrangement of mechanism for effecting this objeet,as hereinafterspeciiiedand claimed.

Figure 1 isa front elevation, partiallyin section, showing a hat-ironing machine containing my invention, a hat being pla-ced upon the hat-block, the full lines showing the iron just applied to the hat preparatory to starting the machine in operation, the dotted lines showing vthe iron as it arrives at the junction of the crown and brim, and also the position which the iron is thereafter made to assume automatically while the ironed hat is being removed 'rom the hat-block. Fig. 2 is a plan or top view of Fig. l, the oval-lathe part of the mechanism being removed and the frame-work 'being partially broken out to show the operadevice of Fig. 3, the latter being shown in section. Fig. 5 is a section of Fig. 2 on the dotted line z z, showing only the parts for oper- |ating the universaljoint contrivance which Y supports the rear end ofthe iron.

Fig.Y 6 is a sectional detail of the chuck and the-devices co-operatingtherewith to confine the hat-block upon the spindle of the oval lathe, the said chuck being shown in elevation in Figs. 1 and 2a. Fig. 7 is a longitudinal horizontal section ot' the iron and its tubular extension, through which are passed the gas and air supplying pipes. Fig. 8 is an under-side view ot' the adjustable guide-plate which controls the movements of the oval lathe. Fig. 9 represents a top view and section of the ways attached to the spindle which rotates the hat-block. Fig. 10 is a top view and section of the disk coinposing the top plate of the oval lathe. Fig. l1 represents in detail the stud carried by the said disk or top plate and its anti-friction rollers extended within the groove oi' the guideplate. Fig. 12 is a detail of the said stud, showing its eccentric portions on which the anti-friction rollers revolve and Figs. 13 and 14, details of' the support for the rear end of the iron.

The frame-work A of the machine, having a horizontal top plate, A', and inclined portions A2, has bearings to properly supportthe working parts. The main shaft B, having fixed on it a pulley, B', driven by a belt in any usual way, has at its other end a bevel-pinion, B2, which engages a bevel-pinion, B3, on and rotates the inclined shaft B, which gives motion to the oval-lathe mechanism and hat-block carried by it, as will be described. vThe shaft B4 has a worn1,G, which engages a worm-gear, D, supported by a stud, D', of a depending bracket, D2. This worin-gear D at one side has connected with it the smaller pinion D3, which engages and drives a gear, D1,ot' about five times its diameter, placed loosely upon the shaft E, which isinstrumental in giving to the iron I its movements to follow the hat from the top of the crown to the rim. rlhis loose Agear D"l has at its side (see Fig. 2) a series of teeth? 'arm G has pivoted to it a sector, b, provided with a curved slot, which receives a pin, b",

IOC

projected from one side of the lever G2. The crank-arm G is provided with an adjustable weight or counter-balance, F. (Shown in full lines, Fig. 1, and in dotted lines, Fig. 2.)

The shaft E, at its rear end, (see Fig. 5,) has a crank or arm, E', connected by a link, E2, with the lower end of an elbow-lever, E3, pivoted upon a suitable bracket, 4.0, of the framework. (See Fig. 2.) The upper end, b2, of this elbow-lever is bored to receive the long end of a pin or bolt, c, (shown separately in Fig. 13 and in dotted lilies, Fig. 5,) and held therein adjustably, as shown, by a set-screw, b3. This bolt has a groove, c2, to receive a pin, c3, inserted through the neck o* of a forked bearing, c, so that the said forked bearing, if desired, may be rotated on the said pin at any time during the vibration of the elbow-lever E3, the extent of its movement being shown by dotted lines, Fig. The fork c5 has pointed screws c6, which enter conical cavities c1G (see Fig. 14) in a hub, cl, through which are passed the air-supplying pipe e and the gas-supplyin g pipej'. This hub receives within ita collar or foot piece, g, which may be rotated freely therein.

The iron I is composed of a metal shell having longitudinal division-plates 3, the said shell being covered at one side (see Fig. 2) with a removable concaved plate, 4, attached by screws 5, and at its opposite or under side, as viewed in Fig. 1, the face of the iron may be either flat or convexed, according to the Work to be done. The rear end of the iron is provided with small holes for the passage outward of the heated products resulting from combustion ofthe gas and air, and with a hole, 42, through which to ignite the gas. Theiron I, at its rear end, has a threaded socket to receive the pipe h, which, at its other end, is screwed into the part g, before referred to, the said pipe h forming the rear extension ot' the iron. This pipe h is provided with a series of small holes, h', which may or may not be covered by the movable sleeve h2, according to vwhether more or less atmospheric air is to be introduced at that point. The gas supplied from any suitable reservoir is conducted along the pipe f, which terminates some distance short of the air-pipe c, which latter is extended into the iron, as shown in Fig. 7, and in prac tice is supplied by atmospheric air from a suitable blower or air-pump or other source for supplying air under pressure. These pipes f care extended through a loose disk, c2, (see Fig. 7,) which nearly fills the interior of the pipe h, the said disk so supporting the pipes efas to permit the pipe h and the iron connected therewith to be revolved axially without disturbing the position of the pipes f e, the part g supporting the rear end of the pipe h then turning, as before described, freely.

In practice the shaft E will receive but part of a rotation, sufficient to cause the elbow-lever E3 to move from the full to the dotted line position in Fig. 5 and the arm G to move from the full to the dotted line position 6. (See Fig. 1.)

The oval lathe is composed ot' a grooved guide-plate, L, (an under-side view of which is shown in Fig.8, 7 being the groove tl1erein,) of a guiding-head, M, Fig. 9, secured to the upper end ofthe spindle B4, and of a disk or top plate, N, adapted to tit and slide on the said head,the plate being provided with a stud and rollers to enter the groove ot' the said guideplate. The guide-plate L is adjustably secured to the inclined part A2 of the frame work by means of bolts S, (see Fig. 1,) inserted through slots 9 in the frame part, and is made adjusta ble on the said part by means ot' the adjusting device 10, (shown as a thumb-screw,) held in a suitable standard, 12, and connected b v means of an annular groove and pin, 43, with an ear, 13, of the said ring. By means ot' this adjusting device 10 the plate L may be placed in a posit-ion more or less eccentric with relation to the center of the shaft B4, thus making the groove 7 ofthe ring more or less eccentric with relation to the center of said shaft. The upper end of the shaft B4 has fixed to it the guide-head M, the edges of which are beveled to receive the lips'k, screwed to the under side of the disk or top plate,N, by screws 7.12. This disk or top plate has a stud, k, fixed thereto by a suitable nut, so that the stud cannot rotate. The lower end ot' the stud is made of two diameters, as at 14 15, (see Fig. 12,) to receive two rollers, 16 l 7, Fig. 11, which are fitted into the groove 7 ot' the plate L, as shown in Figs. 1 and 11, one roller always acting upon one wall ofthe groove inthe said guide-plate and the other roller on the other or opposite wall thereof, thus lessening to the minimum the friction of the parts and avoiding noise.

The plate N has a spindle, N2, (shown more fully in Fig. 6,) which receives and carries the chuck l, (shown scparably in Fig. 2%) which locks the hat-block l2, Fig. 1, in position with relation to the said spindle so as to be rotated with the top plate or disk, N. This spindle N2, at or near its lower end, is provided with short slots or grooves Z3, (see Fig. 6,) to receive the points of screws i4, inserted therein after passing through the lower end or hub of the chuck l, said screws preventing the chuck from rotating when the spindle is at rest, yet permitting the chuck to be moved longitudinally by the large nut P, (see Figs. 1 and 6,) the hub of which is provided with an internal screwthread to fit the screw thread upon a projec tion, m, ofthe top plate or disk, N, such screwthreaded connection being shown in Fig. 6.

The chuck has secured upon it the nut m2, which fits a iia-nged part ot the hand-nut P, thus holding the said lian ged part between the said nut m2 and the shoulder l upon the lower end of the chuck, so that the rotation of the nut P upon the screw-threaded part m of the plate N enables the chuck l to be moved longitudinally on the spindle N2, such movement ofthe chuck in the direction ot' the arrow near IOO IIO

' it, Fig. '6, causing then'pper end of thechuck,

inclined nut m4, the small knobs 'or projections m5 at the upper ends of each of the separate fingers or pieces of the 'elutchbeing .thereby pressed firmly into engagement with the hatblock Z2, into a hole in which the saidchuck is inserted. Rotation ot' the shaft B4 and guidewayMthereon causesthe top plate, N, to rotate with it, andthe rollers 16 17 on the stud 7030i' the said top plate, N, traveling in the groove 7 of the plate L, cause the said top plate, as the shaft B4 rotates, to revolve in an oval path, which may be readily adapted to conform in shape to the shape of the crown of the hat to be ironed.

The shipper-lever. R, pivoted at 19, has an arm, a, which moves the clutch parta,connected by spline n2 with the shaft E, and the said shipper-lever, at its other end, has a link, a3, suitably supported by a guide, a4. The outer end of this link n3 is engaged with the clutch part a5, held on the shaft B by a spline, the said clutch part nliaving at its right-hand side suitable teeth to engage teeth 44 on the fixed part of the frame, and at its left-hand side suitable notches to engage projections 20 at the side ofthe driving-wheel B.

At the under side of the shipper-lever R is a detachiug-lever, p, pivoted at p', the short .end of the said lever entering a notch or slot in a holding-lever,p2, (shown most clearly in Fig. 3,) which is secured to the under side of the frame-plate A by screws p4, and is provided with a notch, as shown in Fig. 3, to receive the shipper-lever R and hold the latter' in the position Fig. 1 whenitis desired to start the machine in operation. This holding-lever (mostly broken away in Fig. 1) has an adjusting device, p5, (shown as a screw,) that operates upon a short latch, p6, which, when it is desiged to stop the motion of the machine to release the shipperlever automatically, is struck bythe finger r, which is connected with the rocking shaft E, the shipper-lever, when the holding-lever p2 is so depressed, being moved by the spiral spring r2, Fig. 2, so as to complete the disengagement of the clutch part a5 from driving-wheel B and the clutch part a from gear D4, thus leaving thelatter loose on the shalt E. The shaft E, during the partial revolution given to it by the worm G, wormgear D, pinions D3, and gear D, then in engagement with the clutch parta, causes the arm G to travel gradually toward the left, (see Fig. 1,) during which movement the lever G2 is gradually lowered into the position indicated by dotted lines 22, so that when the arm G reaches the dotted-lineposition 23 the hat-iron I will be brought into the dotted-line position 24. Just as the arm G arrives in the dottedline position .23 the linger r depresses the holding device p2 and releases the shipper. When the shipper has been so released the weightF on the arm G moves the said arm into the dotted-line position '6; but just before the arm G reaches such position the pi'n b of the lever G2 lneets the lower end of the curved slot. in the link b and throws the lever G up into such position as to leave the iron I in the dottedline position 26, Fig. l.

To stop the machine instantly at any time during its movements, the detaching devicep may have its longerend moved toward the main piece of the shipper-lever R, causing the shouldered end of the detachiu g device p to depress and disengage theholding device p2 from the shipperdever. The descent of' the arm G is arrested by the weight F striking the stop 45, (shown in dotted lines, Fig. 2.) A hat, having been ironed, is removed and the machine turned back to its initial or starting position.

I do not broadly claim a gas-heated iron in a hat-ironing machine, as I am fully aware ot' United States Patent No. 69,950, Octoberl, 1867.

' The employment ot' gas and atmospheric air introduced into and commingled in the iron in quantities controlled by suitable stop-cocks in the pipesfc enables me to heat the iron in a better manner, avoid smoke, and obviate the use of a chimney.

I desire it to be understood that I may employ the iron I in a machine without the oval lathe.

Locating the spindle B4 at an angle of about forty-five degrees enables the hat-block to be rotated about with the chuck at the same angle, whereby the hat is brought into such position that the part operated upon by the iron may be readily seen.

I claim- 1. In a hat-ironing machine, the hat-iron I, having the partitions 3 to form flues, and the rearward tubular extension li, iitted to turn in the hub d, combined with the said hub,its Inovable support, and gas and air pipes, lthe bearin g for the said hub, and the lever to support the said bearing, substantially as described.

2. The hat-iron l, provided with a supported handle at one end and the extension hand hub d at the other, the air and gas pipesf for heating theiron, and the universally-jointed operating connections for the hub d, combined with the lever E3, to automatically swing the rear support of the iron as the iron is being moved between the tip and the brim of the hat, substantially as described.

3. The hat-iron I, provided with partitions 3 and exit-passages at its end, and the pipe h, combined with the hub d, with which it is loosely connected, as described, and with the gas and air pipes and their support l2, located in the pipe h, whereby the iron may be rotated more or less without disturbing the relative position of the said gas and air pipes, as set forth.

4. The hat-iron I, its extensions G2 and It, the shaft E, and its arms G and E', combined with means, substantially as described, to support the parts G and h and move them in a IOC' IIO

line corresponding with the outline of the hat from its tip to its brim.

5. The shaft E, its arm G, link G2, and bearing G3 for the hat-iron extension G4, combined with the hat-iron, the slotted link b, and pin b', substantially as described.

6. In a hat-ironing machine, a hat-iron adapted to be heated by gas,as described, combined with a hat-block and oval-lathe support therefor', substantially as and for the purposes set forth.

7. The shaft B4, its head M, and the top plate, N, and its spindle, combined with the adjustable guide-plate L, to operate substantially as described.

8. The grooved guideplate L and the top plate, and the stud havingtwo diameters, 14 15, combined with rollers 16 17 thereon, each of which bears firmly against one side or wall of the said groove, as and for the purpose described.

9. In a hatironing machine, a hat iron adapted to be heated by gas and air under pressure, as described, combined with a revolving hatblock, substantially as and for the purpose set forth.

10. The hatblock, the spindle N2, and its head m4, combined with the chuck, split, as described, to form separate lingers to engage the interior ot' the hat-block as the chuck is expanded, substantially as described.

11. The shaft B4 and oval lathe operated by it to carry the hat-block, the shaft E, means to operate it, and the tinger r thereon, combined with the hat-iron, means to operate it, as described, and a shipping-lever automatically operated by the said fin ger to arrest the movement ot' the machine as the hat-iron reaches the junction of the crown and brim of the hat, as described.

12. In a hat-ironing machine, a hatiron combined with a hat-block and rotating spindle to actuate the same, the spindle being located in an angular position, as shown, and for the purpose described.

In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses.
